Latest Patents

Ping An holds a patent titled "Fast coarse tuning control for PLL frequency synthesizer." This invention focuses on improving the voltage-controlled oscillator (VCO) of a synthesizer by implementing a coarse tuning method that utilizes a binary search technique. This method allows the VCO frequency to match one of a limited number of discrete reference frequencies efficiently. The coarse tuning process operates without frequency division and phase comparison in a closed feedback loop, which significantly reduces settling time and expands the lock-in range. The fine tuning is conducted using a conventional analog PLL, ensuring precision in frequency synthesis.
